Can someone make a camera App?

I was just wondering if somone could make a new video camera app that can upp the FPS and increase the audio bit rate. The iPhone has the best audio when recording. I think its bit rate is like 80KHZ

[Q] 1080p30 right? so possible to do 720p60?

i imagine the bitrate would be similar
any way to do this?

Someone could hack it wouldn't mind!

i really don't think it's possible .
its hardware issue, the sensor won't be a
ble to take it even with lower than 720p

wouldn't have to be 60fps even though.
anything higher would be an improvement

Video recording needs to be done in a standardized frame rate, 24, 25, or 30Hz (or 50 & 60p). If not, it would be a terrible jitter from pulldown during playback.

plenty of videos are vfr depending on the scene motion state though (although mosty wmv afaik). as long as the player knows the right frame rate to play back it plays back fine
anyway, i was thinking as far as the data rate goes, it wouldn't be much different. if there's some hardware limit that doesn't allow it - fair enough.
what is the highest fps we could get though?

can someone make a getPreviewFpsRange tester?

it would be interesting to see how fast the S5 can actually record video, especially at lower resolutions
the built in "slow motion" "1/8" mode would suggest its capturing at 240fps at 1280x720? Somehow I doubt that.
But who knows what its capable of at 640x480..might be able to capture insanely fast and we could have a really cool high speed video app.
The SDK says: http://developer.android.com/reference/android/media/MediaRecorder.html#setCaptureRate%28double%29
public void setCaptureRate (double fps)
Added in API level 11
Set video frame capture rate. This can be used to set a different video frame capture rate than the recorded video's playback rate. This method also sets the recording mode to time lapse. In time lapse video recording, only video is recorded. Audio related parameters are ignored when a time lapse recording session starts, if an application sets them.
Parameters
fps Rate at which frames should be captured in frames per second. The fps can go as low as desired. However the fastest fps will be limited by the hardware. For resolutions that can be captured by the video camera, the fastest fps can be computed using getPreviewFpsRange(int[]). For higher resolutions the fastest fps may be more restrictive. Note that the recorder cannot guarantee that frames will be captured at the given rate due to camera/encoder limitations. However it tries to be as close as possible.
Can this be taken at face value? I.e. can you really see what the phone will max out at fps-wise at a given resolution?
Could someone make an app to do this test and show how fast it can capture at various resolutions?

Q: Oneplus Two Camera Bitrate -> Push it to the max!

Hi,
I am experimenting with the oneplus two camera, i have cynogenmod 12.1 running with the app "cinema 4k", which allows
to set a bitrate of 200mbps for 4k video. the videos it produces only have 160mbps, so there must be some cap in the
h264 encoder or in the device itself. i guess there will be some hardcoded limit somewhere in the quallcom encoder libraries?
does anyone know what part limits the video bitrate on an android device? i already modified media_profiles.xml to set the
bitrate higher (to 300mbps) but it is still recording at 160mbps.
i would like to test how much the device can handle, and how the video quality would be at 250mbps+
because the camera seams really great for video recording at nighttime
thanks, christian

For those that have it. Quick 4K info..

Whats the 4K recording bitrate and hows it compared to other phones . Also, is there a 5 min limit like on my note4?
--Thx

I did a quick test and got 90MB for 15 seconds, around 6MB/s.
But, I wasn't sure if there was some way to stress the bitrate of the codec - bright scenes? dark scenes? high contrast? If anyone has any insight into which are the hardest scenes to compress I can repeat the experiment.
Or, is the codec somehow a constant rate codec (as in fixed rate MP3 vs variable rate)?

how about the time limit? how long can you record 4K?
I think 6/MB is average. I heard of people that root note 4 able to up the bitrate. Even if it is the same it still might look better then other phones with the same bitrate due to the lens and so forth. I think the main issue is going to be with the stabilization. OIS helps but I guess you can run it through adobe or some other program to get software to add to that. I wonder if I record in 1440 if the software will work for that.
